My invention aims to provide improvements in separable sliders for multiple operated fastener installations.

In the drawing which illustrates a preferred embodiment of my invention Figure 1 is a plan view of a .portion. of a multiple operated fastener lnstallatlon showing my improved slider in normal operating position;

Fig. 2 is a view of the installatlon shown 'in Flgure 1 showing the manner of operation of the pull tab to disengage the hinged parts of'the slider; i

Fig. 3 is a view of the parts shown mFigs. 1 and 2 but showing the hinged parts of the slider in position to permit removal of one of the series of fasteners from the slider; Fig. 4 is a section taken on the line 4-4 of Figure 1; and u Fig.. 5 is a section taken onithe lme 5-5 of Figure 1. j

Referring to the annexed drawmg whlch illustrates my invention, I have shown a slider which is divided into movable connected parts so that at anytime it becomes desirable one of the series of fasteners attached to one of the stringers of a multiple operated fastener installation may be entirely removed from the slider. It has been found that multiple operated fasteners 1nstalled upon certain articles of wearing apparel are subjected to uses of such. nature that sometimes the fasteners on one Stringer become jammed with the fasteners of another stringer or become disengaged in such a manner that the slider cannot function pro erly.

e installation illustrated includes a Stringer 1, a Stringer 2 and separable fastener members 3 of any desired construction attached to the adjacent edges of the stringers 1 and 2. Portions only of the stringers 1 and 2 are shown because itis not necessary togo into detail with anypart of the installation other than the slider. The particular slider construction illustrated in the drawing comprises a body member having a bottom plate portion 4 and a top plate portion divided into a fixed: part 5 and a movable part 6, as shown in Figs. 3 and 4. The

7 which overlaps the fixed part 5 for the purposes hereinafter described. The pivot for the pivotally mounted part 6 (Fig. 5) is in the form of a rivet 8 passing through the fixed portions of the slider at one end.

Wlule the movable part 6 of the slider may be moved from a position shown in Fig. 1 to a position shown in Fig. 3 to permit removal of the fasteners of one of the stringers from the slider in any suitable manner,

I have shown a simple and eiiicient means for accomplishing the desired results. The slider illustrated has a strip portion 9 extending from the lower edge thereof and integral with the fixed part 5 upwardly in slightly spaced parallel relation for a substantial distance and is then bent outwardly and then upwardly to form a loop 10, as

shown in Fig. 5. The portion 9 has its free end extending through the fixed portions of the slider (Fig. 5) and has the extreme end upset `to support the end of the loop 10. A pull tab 11 is pivotally attached to the loop 10 for operation of the slider in the usual manner. This pull tab has a relatively large aperture 12 adjacent to one end and through which the loop 10 passes in substantially spaced relation so that the pull tab 11 may be moved relative to the loop 10 in a plane parallel with the plane of the slider. Y

When the movable part 6 of the yslider is in the osition shown in Figs. 1, 4 and 5 the iiange is frictionally gripped between the portion 13 of the member 9 and the face of `the fixed part 5, thereby holding the movable part. against accidental lateral movement. When it is desired to move the part 6, the pull tab 11 may be swung laterally with the loop 10 acting as a pivot, as shown in Fig. 2, thereby causing a projection 14 on the pull tab to en age the flange 7 and force it from between t e portion 13 and the part 5, as best illustrated in Fig. 2. After .the movable part 6 is freed by the projection 14 it ma be readily swunglinto a position' such as s own in Fig. 3. T c part 6 may be returned from the position shown in Fig. 3 to the position shown in Fig. `1 by merely swinging it about its pivot and forcing the flange 7 in between the portion 13 and the part 5.

It is believed that anyone skilled 1n the art will readily understand the utility of applicants divided slider device, because when the parts are arranged'as shown in Fig. 1 the slider may be used in the same manner as a slider of the non-separable type to lock and unlock the fastener members 3. However, if at any time it becomes necessary to correct alignment of the fastenenmembers of one Stringer with the fastener members of the other Stringer, the pivoted part 6 of the slider may be moved from a 'position shown in Fig. 1 to a position shown in Fig. 3 and the fastener members on the strin er 2 can be lifted upwardly and out- -wardtly from the bottom plate portion 4.

' After the fastener elements have been properly rearranged the slider may be returned to the lower end of the stringers where the fasteners of the Stringer 2 may again be inserted into position in the bottom plate portion 4 and the movable part 6v returned to its normal operatingk osition. Thereafter the slider may be pu led upwardly to engage the fastener members 3 of the Stringer 1 with the fastener members 3 of the strin er 2.

Since 1t is desirable to hold the part 6 rmly in position with relation to the por-y tion 5 of thetop plate part of the slider the pull tab 11 provides a very eiiicient lever which can be much more easily operated to disengage the parts 5 and 6 than would be possible without the use of the combination pull tab 11 and projection 14 or some other equivalent structure.

While I have illustrated and described a i preferred embodiment of my invention I do not wish to be limited thereby, because my invention is best defined by the following claims.

I claim:
